An earthquake measuring 5.6 on the Richter scale shook Mianzhu City, southwest China's Sichuan Province, at 2:03 a.m. Tuesday, said China National Seismological Network, Xinhua reported.
The earthquake, with the epicenter monitored at 31.5 degrees north and 104.1 degrees east, was felt in five other areas of Sichuan: Chengdu, Deyang, Mianyang, Guangyuan and Aba, according to the Sichuan Provincial Earthquake Bureau Tuesday.
A bureau had received bo reports of fatalities, but it warned of the possibility of aftershocks, including some measuring 5 on the Richter scale.
The Emergency Response Office of the Sichuan Provincial Government reported no casualties in Mianzhu, one of the areas hardest hit in the 8-magnitude quake on May 12 last year.
The office, together with Sichuan Provincial Earthquake Bureau, dispatched a special working group that joined workers at the site of the epicenter an hour after the quake to inspect the damage.
They found no visible damage in Zundao and Jiulong townships of Mianzhu, where housing was rebuilt after last year's quake, except for some cracks in old and reinforced homes.
The quake toppled three houses in Tumen Township, also in Mianzhu, while telecommunications, power supplies and transport were disrupted in Qingping and Tianchi, two other townships in Mianzhu. One woman worker in downtown Mianzhu suffered injuries to her hands while attempting to open a door when the earthquake struck.
Luo Yingguang, head of publicity with Mianzhu City Committee of the Communist Party of China (CPC), confirmed Tuesday a road to Qingping Township collapsed in the quake, stopping transport, plus disruptions to power and telecommunications.
Repairs to the road were underway, said Luo.
